The test experiment was conducted inside one sugar beet (Beta vulgaris L.) located inside the Selhausen study area. The study area lies in Northrhein-Westphalia province of Germany between the cities of Aachen and Cologne. With an approximate size of 27 km\(^2\), the site is part of the Tereno network of environmental observatory infrastructure and, therefore, an object of intensive research. One aspect of this research is the annual overflight by a hyperspectral sensor specifically designed for SIF retrieval (HyPlant). The area itself is predominantly used for agriculture with cereals and sugar beet making up the largest proportion of crops grown. The climate is oceanic with mean annual air temperature around 10\(^{\circ}\) C and mean annual precipitation slightly above the country average - around 700 mm.
